Background: We have identified a novel tandem duplication leading to ubiquitous expression of the agouti-signaling protein (ASIP) in a female patient with severe early onset obesity, red hair, tall stature, and insulin resistance (Kempf, E. et al, 2022). Due to the ectopic expression, ASIP - which normally is only expressed in the skin - can interact with the Melanocortin-4-Receptor receptor in the hypothalamus thereby causing the obesity phenotype. <p cla...
